Blue Color in Another Manner

Take 1 pound of indigo and 2 oz of alunite and one ounce of raw honey. Boil in a strong lye solution made from oak wood ashes until one-third of it has boiled away. Afterwards dye with it--the yarn will be a beautiful blue: Or: take 1 pound of fine 'Venetian Soap', 1 ounce verdigris. Let boil together until one-third has boiled away. Thus it will be an outstandingly beautiful dye.
